5 Claims. (01. 16-496) The inventionvrelates to tracks of the type normally supported from overhead and adapted for carrying sliding doors, conveyors and the like and more particularly to an improved track which is simple to construct and install.

It is the general object of the invention to provide a new and improved track of this type.

Another object is to provide a track comprising a pair of angle members having one flange of each positioned in laterally spaced parallel relation and provided with integrally formed projections which serve to space the angle members apart and to secure them together.

A particular object is to provide such a track wherein the projecting portions are produced by deforming the parallel flanges f the track members at uniformly spaced intervals so that whei two angle members are assembled the projecting portions register and permit the members to'be secured as by riveting, welding, etc.

Other objects will become readily apparent from the following detailed description taken in connection with the accompanying drawings in which: i

Fig. 1 is a fragmentary side elevation of a section of the track embodying the invention.

Fig. 2 is a top plan view thereof.

Fig. 3 is a bottom view.

Fig. 4 is a section along the line 4-4 of Fig. 1.

Fig. 5 is a section along the line 5--5 of Fig. 1.

Fig. 6 is a fragmentary top plan view of a modified form of the invention.

Fig. 7 is an enlarged section along the line 1-1 of Fig. 6.

Figs. 8 and 9 are fragmentary top plan views of additional modifications.

While there is shown in the drawings and hereinafter described in detail a preferred'embodiment of the invention together with three modifications, it is to be understood that various other modifications may be made by those skilled in the art without departing from the spirit and scope of the appended claims.

As shown in the drawings, the invention is in the form of a double angle track comprising a pair of angle members Ill and H arranged in parallel spaced relation with their horizontal flanges [2 extending outwardly as shown in Figs. 4 and 5. Generally the track is hung overhead by means of a plurality of hangers, one of which is shown at l3. These hangers are formed of rods which extend downwardly between the vertical flanges of the angle members and have fixed collars l4 and nuts l5 thereon for clamping the track therebetween.

In the form illustrated in Figs. 1 to 5, to space the angle members apart the adjacent flanges thereof are provided with integral deformed portions H5 at uniformly spaced intervals. The deformed portions of a pair of angle members, when placed face to face, as shown in Fig. 2, provide slots l8 between the angle members to admit the hangers [3. The deformed portions are secured together as by welding or by rivets [9 or other suitable devices. I

The deformed portions l6 are preferably formed in the angle members at the time they are rolled or otherwise when they are in a heated condition, to produce track members as illustrated in Figs. 6 and '7. They may also be formed in angle members of high carbon steel by partially slitting the flange adjacent the projecting portion as at 20 and pushing the metal out to,

form the desired lug, as illustrated in Figs. 1 to 5. The exact shape of the end portions of the lug will depend somewhat upon the character of the material and the stock required to provide the necessary amount of stretch. The lugs are produced at uniformly spaced intervals so that a pair of angle members of identical formation inaybe arranged alongside each other and secured together to form the track in lengths of ten feet or other customary lengths. The end lugs are preferably spaced equally from the opposite ends of the angle member so that when ficient size to leave a space IS the same as that.

shown in Figs. 1 to 7. This construction permits the use of one angle member of standard form gogether with a specially formed angle member In the form illustrated in Fig. 9, angle members 23 and 24 are provided with deformed portions 25, each of a size to produce the entire space l8 between the angle members. However, in this form the deformed portions of one angle member are located intermedaite similar deformed portions of the other angle member thus track.

permitting each angle member to have approximately one-half of the deformations of the angle members shown in Figs. 1 to 7. The forms of the invention illustrated in Figs. 8 and 9 have the advantage that the spacing of the deformed portions does not have to be sufiiciently accurate to match with similar deformed portions on an adjacent angle member.

It is believed. that the merits of the invention are readily apparent. From a production standpoint the angle members of the forms illustrated in Figs. 1 to '7 and 9 may all be made duplicates and then assembled in pairs. If the rail is formed hot the lugs are formed simultaneously and no further work is required in the fabri-' cating plant. If the rail is punched and formed in the same operation this is also true. Furthermore, the spacing lugs are virtually furnished without cost either as to material or labor. At

the time of assembly it is not necessary to handle a third member such as a loose bushing or other device and therefore the assembly operation is greatly simplified with corresponding saving of labor. The angle members may be secured toether as by spot welding, riveting, etc., and

thereby provide a double angle track section of. rigid construction.

I claim:

l. A track comprising a pair of thick, rigid metal angle members with narrow flanges p'osiangle members to the first deformed'portion at one end is equal to that at the other end of the 3. A track as defined in claim 1 wherein the deformed portions comprise parts of the flange of the angle members bent outwardly to form lugs with flat abutting surfaces and the angle members are secured together by rivets.

v 4. A track comprising a pair of thick, rigid metal angle members with narrow flanges positioned with one flange of each in laterally spaced upright parallel relation to the other and having deformed portions which extend the full breadth of said parallel flanges projecting at uniformly ..ispaced intervals from said parallel flanges, the

deformed portions of one angle member being located intermediate those of the other so that the deformed portions of each angle member abut normal flange portions of the other angle memher, and means for-securing said deformed portions to the abutting flange portions to form an integral track unit.

5. A track comprising a pair of thick, rigid metal angle members with narrow flanges positioned with one flange of each in laterally spaced upright parallel relation to the other, one of said angle members having deformed portions projecting from one flange thereof said deformed portions extending the full breadth of said flange and abutting opposite portions of the parallel flange of the other angle member to space the angle members apart and form slots therebetween for admitting hangers and means for securing the deformed portions of said one angle member to the adjacent flange of the other angle member.
